Is there any plan to support Chisel5 and CIRCT?

Motivating Example

I'm developing a RISC-V CPU project based on chisel5. And I want to use firesim for performance simulation. However, firesim is currently using Chisel 3.5, which is hard to bump due to some other modules from Chipyard.

Basically, after I take a look at the code, I think the roadmap of reinventing firesim Transform contains following steps:

• Verification API can be replaced via single CIRCT transform to visit all verification transforms to generate corresponding MIDAS interface.
• Annotation of MIDAS can be replaced via Chisel 5 XMR API.
• Transform of GoldenGate can be replaced via single CIRCT transform to capture all clock and multiple Read/Write memory.
