No, not yet. The probelm there is more one of drivers than interface.
At the interface level, it's ben done by a russian chap. The problem with
that design is it's PIO driven and as a result slower than putty. A good
IDE interface wtih DMA has the potential to rival some of the faster
interfaces used on Qbus as it would not have all the protocal overhead.
I have adaquate devices for my PDP-11s but I'd love to build a small
T-11 powered box. Two limitations to doing that, an extreme shortage of
time and a free OS I can write a driver for (RT11 and unix don't count).

Silly question, why bother with MSCP at all? A native drive like RL02,
DSD-880, RKnn would work just as well and offer better performance.
Answer, it's a standard that everyone seems to emulate.
Besides CP/M based systems are where I hardware hack the most.
