This is a good question but I do not know the answer.

I would use Simh to boot a BRUSYS tape then copy the tapes to make a
bootable disk.

   The closest RSX11M (not Plus) distribution I can find is an RL01 distribution of RSX11M V4.1
Since it is disk and not tape it can be directly booted with Simh and it does have a ICP.TSK
that should be pretty compatible with V4.2 since it is from V4.1 Baseline.

You can find this RSX11M V4.1 distribution at:

It will unzip into 6 RL01 disk images and 3 update E disk images.
Below I mapped the first two disks and found a copy of ICP.TSK
on the 1 disk which is a Baseline image that should run on a range
of different hardware.

Total of 260./260. blocks in 3. files

from the RL01 image you should be able to PUTR read and then write to an RX50
as you have done before.

Good Luck,
