I am redoing some wiring in our house that involves breaking and remaking
some original connections -- ripping out and replacing boxes by larger
(e.g., two-gang by three-gang). I find that in some cases all the
conductors of the same color have been connected using crimps that have
then been taped over -- even the hots. Is this kosher? Surely wirenuts
provide better insulation than the tape. There could be 220/240 volts
between conductors in some boxes because there are Edison circuits
involved.

Should I use wirenuts for the reconnections? Crimps and tape take up less
room.

And, while I think of it, is it OK to have circuits fed from different
breakers in the same box (e.g., outlet and light switch)? One could
assume that since the one circuit is dead (switched off at the panel),
the other is too.

I would avoid crimps for just one reason.
What if you had to replace an outlet, light fixture, or switch that went
bad, or wanted to upgrade to the latest and greatest fixtures or switches?
Would you rather just unscrew a wirenut, or try to get the crimp off with
a pair of pliers?

Two things:

If you can remove a crimp using pliers, it means the crimp wasn't installed
correctly in the first place. If you need to change a connection, you cut on
either side of the crimp. If you're running new wiring, you leave extra in
case you need to cut out a crimp. If it seems that existing wiring is
already too short to allow cutting later, use wire nuts.
