You could take a look at the dynamic timeslot implementation, i.e.
bts_model_ts_disconnect() and bts_model_ts_connect(). The way it looks is that
all you need to do is to set the new config of the channel. After all,
osmo-bts-trx has no lower level hardware to be instructed to do anything, it's
all in the structs in RAM: bts_model_ts_disconnect() for trx is empty.
bts_model_ts_connect() basically just sets the new TS config using
trx_set_ts_as_pchan(). I asked myself the same question back then, and in the
end found out that simply setting the new config works fine.
I hope that helps ... and is even related to your question :)
