there a lot of issues in every aspect...
1. power, the least issue. GT3 engines are basically road engines, throw away restrictors and mandatory turbo pressures and 600hp are quite reachable. Surely would be required a 120L fuel tank for the race and a better cooling system but being dtm a sprint format, there will not be many reliability issues about this. Gearbox should be fine too.
2. aero and chassis. The biggest issue. Basically all gt3 cars stock and unballasted are >1200kg, it's really unlikely drop some other mass from them since chassis need to be the same of road cars and all other features are already reduced to the essentials. The only way to save some mass would be drop off all electric stuff that manages ABS, TCS etc...
but no way will be possible to make them 1070kg heavy (DTM reg. min. weight). Considering also that 1070kg is driver included... basically a dtm car weight is <1000kg.
Aero, well... basically no match. You can give bigger splitter/rear wing and a GTE-like diffuser but a GT car will never develope the same downforce and cornering speed of a dtm.
3. maybe the only positive side of the matter.... I'm quite sure gtopen/IMSA michelin are way way better than dtm hankook compound that are made just to force driver to change tyres due show necessities (like pirelli in f1).
so making a quick comparison
2019 DTM hockeneim fastest pole: 1.28.9
2019 gtopen hockeneim fastest pole: 1.36.7
considering that gtopen gt3 use michelin and are usually a bit lighter than SRO/FIA bop, well these GT3+ need to improve of just 8 seconds at hockeneim
as said... good luck.
Forgot a little detail... all these updates required will increase production and racing costs... so... live and let (dtm) die.
