It would be an awesome chance for FIRST alums at RPI to get a chance to help out and volunteer at the regional! There currently isn't a huge FIRST program at RPI and this would be a great way to get it going again.
The armory would be a bit small, but would probably still work. Will probably be a bit tight like the WPI regional. ECAV would really be the best option as it is a huge facility with a decent amount of nearby parking. The Houston field house would work as well.
Honestly, if they are looking for a location for a regional in the capital region, RPI is a great campus for it. It would also be a chance for students to look at a great potential option for college. (Gotta rep my school
