I'll note that the Tier-2 alternatives have been settled and they're building HRT-3. That's pretty well set in stone at this point.
But doing a drop-in replacement of LRT for BRT wouldn't work on the I-20 plan. The BRT is proposed to run in HOV lanes. Street running of LRT trains works, but I know of no location that has street running on the highway. LRT would still require a separate, dedicated guideway which is one reason LRT for inside I-285 was also rejected. You still run into the same shoulder width reductions that HRT would. The underlying structure for LRT vs. HRT isn't very different. For I-20, once you've gone to all the hassle of the guideway, why not just run the heavier, longer, faster trains on top?

If and when the I-20 inside the Perimeter has the demand for HRT, then fixed guideway can be built along I-20 or underground. Whne the Wesley Chapel Station is built, it would be smart to add switch and infrastructure for future HRT along I-20 to downtown.

Do they expect people to use the bus to get to the stations? I'm not very familiar with that part of town, put I don't recall those areas along I-20 as being very walkable. I would think the point of these stations is for them to be commuter stations. How do they plan on doing that with minimal parking?

Sorry if this has been discussed, new to this topic.

The bus routes are heavily used in this area, also there is not much land for parking structures. People could ride bikes to the stations?

The closer in areas such as Glenwood Park, East Atlanta Village, Grant Park are getting fairly walkable. I live just a couple blocks from a stop (near Glenwood Park) and would walk over to it for sure. But I assume buses would connect others too.

You could even run service along the Blue line to Stonecrest in the morning and evening peak times for people needing to reach Decatur and such.
I completely agree with this. Now you'd have a kind of "express" rail into town and not have trains literally skipping stations along the current "East line."

Any word on funding and timeline to break ground?

They're currently doing the federal Environmental Review. Once this is done, they can apply for FTA grants and loans and such. As for time, minimum 7-10 years before start of service. They have to finish the EIR (18 months, started November 2012 I believe), then design everything, then actually build it. It involves tunnels under highway interchanges, and completely demolishing and rebuilding Indian Creek so 7 to 10 years for start of service is not unreasonable. Hopefully they can build it out in phases. Get Indian Creek to Wesley Chapel going, then add a station at a time going east, but this is just hopefulness on my part.

It sucks that GDOT requires the fixed guideway to be underground at freeway interchanges, instead of zooming above them. It would save hundreds of millions.

Some of what I'm saying though comes from the public meeting back in October so that document doesn't contain everything, but you can see the proposed service map in Chapter 1 I believe.
Without adding track, they would have to time the trains so that the trailing Green Line express catches up to the Blue Line train just after it's terminated at Indian Creek. There is precedent, as the Norristown High Speed Line near Philadelphia operates a two-track line with express service.
Now BRT would take care of the right-of-way issue on I-20, ITP. But how the heck are they gonna swing the Blue line south down 285? There's really not much room east of Indian Creek to maneuver.
