My first question is what pass are you going to buy, Epic, Ikon, Indy, or something else?
Re Epic, I had one for a nine week cross-country skiing road trip I took in 2015. The last four weeks (mostly month of March) were in one condo in Silverthorne. It was a fine location for that pass. I enjoyed excellent variety while sleeping in the same bed every night; skiing Keystone, Breck, Vail, Beaver Creek and even A-Basin was on that pass then. That could be a fine choice for your plan.
Re Ikon, it works well for CO and Utah. In CO you could ski Copper, WP, Steamboat with base Ikon and those plus Aspen with full Ikon. Skiing a bunch of those could entail lodging relocations or longer commutes. Utah, With base ikon you can ski Solitude unlimited and then multiple days at Brighton and Snowbird. With full Ikon you can ski those plus Alta and Snowbasin. Utah is a further drive for you, but you could sleep in one location in the Salt Lake Valley the whole time and hit all the above fairly conveniently.
Re Indy, someone else will have to comment. Seems like Rocky Mtn indy places are somewhat scattered, this could be really fun if you want to get off the beaten path.
Other options are buying something like a Monarch or Cooper season pass and skiing some of the reciprocity places that come with that pass.
