Some inspiration:
This was based on an idea by TaiidanTomcat. He wanted to Soviet-ize an F-16 and asked me for a profile. MiG-21-ish canopy, spine and brake chute housing, as well as MiG-23 ventral fold-away fin. Also two fins. Because... why not? Maybe something more MiG-21- or 23-ish for the fin wouldn't look out of place either.

MiG-21Sh (Shturmovik) ground-attack. MiG-27 nose. Side intakes inspired by Republic's RF-84F Thunderflash.

Ye-8/3. Inspired by the Ultra Sabre (as if that wasn't obvious...).

MiG-25 with canards and mid-set wings. I had a top view of that with several styles of wings (delta, cranked delta, original Foxbat wings,...), but I'm afraid that one was lost "a few PCs back".

I'm thinking of a modified Ye-231 with the lift engines removed and replaced by fuel tankage and ammo storage for a Gsh-23 under the fuselage as on later MiG-21's as well as canards on the inlets similar to those on a Kfir (thinking of using unused ones for a Ye-152M built without them.
I like your thinking!
