No that's not possible as mergecap will print this error message:

mergecap -w out.cap http.cap wlan.pcap
mergecap: Can't open or create out.cap: Files from that network type can't be saved in that format

You can force a new encapsulation type with -T (e.g. ether), but then Wireshark cannot dissect the included wireless frames.

...and if you try to use -F to force the output file to be a pcap-ng file, the resulting file won't be readable, due to bugs.
