Is it possible to set your Boost Wi-Fi network name the SAME as the main Telus modem network name?

Lotus99,

Yes, it's a full modem / router similar to Actiontec but ensure to see my note #2 below.

Well, it's a really convoluted story but here it is. Initially, I complained to Telus why I wasn't getting the speed I was supposed to get (750) and I was getting about (250) wired. They said they would send someone to investigate and made an appointment.

In the meantime, while I was waiting for the above appointment, I had another Telus guy drop off an Optik TV box, for an unrelated matter. Our conversation kind came to my problem above and he said he's also an Internet technician and he'd would look. As it turned out, it was a cable (seriously) that was defective and he replaced and everything was great. That's when he saw my (unused) box of boosters, that I had got from some promotion some time ago -- I didn't use them because of basically the reasons that you have (that it was just another access point for me, not mesh, and my router was powerful enough for my use). He just said, Telus has this new white modem that works with these boosters now that would give me the mesh network and I can get better coverage as a result. He didn't have one but asked me to keep the (above) appointment and he would tell the guy to bring the white one... and he did. 

A few notes for you:

1. It didn't appear (to me at least) that it would take a lot for them to swap out the existing modem with the new one. However, I wonder, for you, if you tell them that your boosters don't work as intended (i.e. you got the boosters to use them as part of mesh network but they are giving out different SSID at the moment) and if they have any solution for this (and that you heard about the white modem being able to do this). If it's presented as a problem, they may able to "troubleshoot" for you. (Keep in mind that after the first Telus technician, I technically didn't have any issue, but they still swapped).

2. Before you commit, please note that Actiontec T3200M is a far better "router" in terms of user / advanced settings. There aren't a lot of settings you can play around with the white one. Don't get me wrong; it does have all the typical settings (wifi SSID, pass key, parental settings, etc.), but advanced features like bridging or an option to disable "smart steering" do not exist in the white one, or at least not yet. "Smart steering" is enabled by default and cannot be disabled. The Telus technician said they "may" update the firmware down the road for additional settings, but he thought that this might have been done on purpose so people don't mess around with the "mesh" settings and what not.

Lastly, as to your question below, here is my experience with that. I did exactly what you did in my previous ... set up. It doesn't cause any issues in terms of being able to use your WIFI. However, if your connection requires continuous connection (e.g. a game where you get dropped off / disconnected if the game notices you swapping networks), then it will happen, as you move around the house while, for instance, the game is playing. Other than that, my devices usually were quick enough to change to the "working" SSID without me noticing. What happens is (at least it's my guess)... your device does not get strong enough signal and it disconnects you from the WIFI and then it immediately seeks another WIFI network and finds the one (with the same SSID) being broadcast nearby and simply connects to that one. As I said, the process was quick enough that I didn't notice anything (other than games) but your mileage may vary.
