merging games like DCC Crawljammer and Umerica questions

[Rob the hopeful gm]

Hello,
I just bought DCC, Crawjammer and Umerica and I wanted to combine them into something along the lines of Mad Max and Firefly had a baby and it knew magic.
So, first, is this the right place to post questions about combining these 3 together? If not, where?
I am pretty sure I am not reinventing the wheel with this so does anyone have anything they can share about how they did this?
I am sure I will have many more questions as I delve into this but I wasn't sure if this was even the correct place to start.
Thanks in advance,
Rob

Toronto Crawl Classics opens the door wide. Maybe I can help.

What questions do you have?

I am trying to get a handle on the best way to incorporate some of the classes and spells from DCC into Umerica without really unbalancing the classes in Umerica. The space portion is easier but I was looking at some of the weapons and spells in DCC and comparing them to Umerica and I am not sure how to balance it.

Can you provide a specific example?
