Technically they had the ability but they very rarely ever did. They didn't need to fly very long missions. Most of the times they were flying defense over Italy. The geography they had to cover was localized. I believe somebody said the only planes that ever used them were some recon missions, but this is hearsay.
The bombs would be pretty useless in AH terms. Again, they weren't doing much attacking. They were focusing on fighters, bombers, and air threats. I can't say I've ever heard of a single C.202/5 with bombs.
I definitely would use those DTs, as I'm a big fan of the C2. I'm just not sure HTC will ever add them.
