Forth, CP/M68 could be compiled for it. I'm sure TinyBasic can be done

I think it'd be fun too, and if somebody else made one I'd buy one, but as
a product -
- there's no legal software you can run on the T11 (and no, RT11 isn't
legal!) from Dave Dunfields TB in C. the nice part is anyone
with a PDP11, LSI11
or sim (including Ersatz-11) can build an image and test it.
- there's no lights and switches front panel
option for the T11
It a micro much like 8085 so yes it can be done. But a small SBC with 32kw ram,
2kw rom and some serial IO is a tiny thing.
- there's no source for T11 chips except to steal
them from old hardware
like RQDX3s, etc
That's a bit harder but far from impossible. considering DEC used them in
Falcon boards, and the the qbus slave (kxt21?), Vt240/241 series, and the
storage hub (something mumble50).

Do you mean the HSC50? If memory serves, it's based on the F-11,
not the T-11. Later HSCs (70, 90, etc) were based on the J-11.

Verified visually just now.

Hang LEDs off a latch, if you want them...
Dare I say, clone in an FPGA?
