I'll import new cockpits for them.but he100 / he112 use a same cockpit(He-1xx) now.
Ah I see.
Great idea, since currently we don't have any really suitable stand-in cockpit available for those Heinkel fighters.

As per the 112's performance, as much as I understand from the several books I've read, the plane itself was fine and it was a good match for the Jumo 210 powered 109s (A, B, C, D).
Most frontline pilots who got the opportunity to fly both, liked the 112 better than the 109.
Nevertheless the early 112s had a flat spin flaw and all in all the 109 was much easier to manufacture and had bigger development potential.
Those who claim that the 112 would have been the better choice or at least should have been followed up upon are wrong IMHO, since the fact that the 112 was a match for the early 109s didn't negate the fact that the DB601 powered 109 E and their follow-ups were clearly superior to anything that could have been done to the 112.
Actually the existence of the He-100 gives prove to that fact, and it's debatable whether the He-100 would have made a difference if it was entered into mass production, but it's safe to say that Heinkel eliminated all significant flaws of the 112 design when they built the 100, and the result was a very promising aircraft.
