A Single-Cycle 64-Bit RISC-V Register File
There are some MCUs that use RV32E also - the CH32V003 [0] comes to mind.

2x 2538 SMD LED for the key switch. How do I make this workout?
Higher interest in the mechanical issue. Kailh box aren't made for 5050-equivalent-sized LEDs so the best I can come up with is placing them on a daughter board with some distance and just accepting losing some light. Probably will use a low-cost microcontroller and R2R leader (current sink) to make them addressable. Alternatively, make use of the 11 bit PWM and LC filter while the ADC forms the feedback loop. Currently unsure if I go with WCH CH32V003 (https://github.com/openwch/ch32v003) or Padauk MCUs. A couple of kHZ PWM should be fine but if I make a PCB I might as well just go all in with PWM-free.

Recommend MCU with dual USB - one host and one device IF?
If you are willing to try r/RISCV ones, then nanoCH32V203 (with two Full-Speed interfaces) and nanoCH32V305 (with one Full-Speed and one High-Speed interface) might be enough.

RP2040 based MCU for dactyl in the works
There are dual USB r/RISCV boards with GPIO pins exposed, like nanoCH32V203 and nanoCH32V305.

USB on pi pico
There are RISC-V MCUs that have two USB interfaces, but those are not supported by QMK yet. I tried some of those boards in kite project.

What is the go-to MCU if you need more pins than a promicro/elite?
u/Bounty1Berry is exploring RISC-V nanoCH32V305 board, but it's a new board that is not supported by (Q|T|Z)MK yet, so not really go-to option at this stage.

nanoCH32V003 board
Their earlier boards like nanoCH32V203 and nanoCH32V305 were more user friendly, one could flash those via USB without WCH-Link.
-
Hardware/software to run RISC-V ASM?
Muse Lab has MCU boards like nanoCH32V203 and nanoCH32V305.
