Combine doom2 and udmf format maps together?

[Hell Interface]

I made my first map doom in doom2 format and I just started making another in zdoom in udmf format.  Way more options and stuff in udmf.  Will I be able to combine these even though they are in diff formats into a 2 map .wad when I'm done as usual?  map01 then map02 etc..

For just playing the maps, yes. ZDoom based ports don't care about multiple maps of different formats in the same WAD, so long as markers and lumps are all where they need to be.
