So basically the Clantech equivalents of most Lostech equipment and construction options? At that point I think you can pretty much just make your own versions of the invasion omnis with the occasional tweak to get around lacking the smaller ER Lasers and having to use Inner Sphere equivalents of non-weapon equipment. (e.g. AMS, Active Probe, ECM, ect)
But since the challenge is for explicitly mixtech mechs I'll start with a mech that is explicitly gaining from both techbases, a Berserker C3 upgrade:

To activate TSM, run fire the ERPPCs, 2 MPLs and 1 small laser. Then you can run and fire both ERPPCs heat neutrally on the way in. Once you're closer you can switch to walking and firing the 4 MPLs and 1 ERPPC or running and firing 3 MPLs, the flamer and 1 ERPPC. Any time you're short on heat the flamer and the 2 small lasers can be substituted in even if you're out of range to keep things balanced. You're providing C3 spotting to your allies and it takes 2 separate Angel ECMs to shut you down directly. Chase down heavys and assaults and stick the axe in their face for 40 points of concentrated damage that'll armour breach most locations even if you haven't managed to soften them up on the way in and then hose them down with machine guns if they're still standing.
If you had all clantech available you'd probably replace the small lasers and flamer with ER micro lasers and a clan flamer, switch to clan CASE II and possibly swap the Hatchet for Talons, but the difference is fairly modest.
