Well, kind of the point, right? Just like the Red/Orange Line orders that are basically the exact same with different dimension shells - yeah, the Type-10s as-is would be ridiculously oversized for the Mattapan line, but, that doesn't mean they couldn't do an addon with smaller dimensions. Hell - a half length test fleet might be great as the first round to do burn in testing for the rest of the order.
Certainly possible from a technological standpoint, but the economics would probably be fairly lousy on a sub-fleet that small, plus the fact that the best-case scenario for the T9s is that they stick around as GL spares while they still have a good bit of life left means that chucking them is unlikely to be nearly as good, financially speaking, as using up the remainder of their economic service lives (Mattapan needs so few the rest will be able to serve as parts donors for a good long time) rather than paying to buy new and sinking the cost of the unused life left in the 9s. By all means, though, when the 9s are coming up on their end-of-life, maybe go for a T10 (or T11 if it's that long from now?) derivative as their successor, but it probably just doesn't make sense right now.
Never going to happen in the next few decades. At the community meetings if anyone so much as hinted at a full Red Line conversion the public was ready to string them up. The MBTA liason/head engineer also claimed there wasn't enough room in the ROW in Cedar Grove for a HRL conversion (lol).
I mean, no one says that you have to have stops converted exactly where they are now. It would be ludicrous to have a Mattapan conversion fall apart because of difficulties in station siting that could be solved by rationalizing the station placement.
That said, it's, as you said, irrelevant as long as the community around the line is on hair-trigger to politically destroy anyone who tries to touch that line. Honestly, they've got good reason to be ready to blow up about it if you ask me. The number of times the T has floated the undeniably-worse bus replacement option is scary enough, but there's also a long history of inferior replacement of existing service that cautions against letting things be touched at at all. The memory of the Elevated and the "equal or better replacement" lie looms large in the minds of anyone being promised improvements if they only agree to allow their existing service to be changed. Re-establishing trust is going to be a hard task, but it's gonna be necessary if ever actual Red extension is something they want to get done.
