Since you are talking in terms of a temporary xfmr for testing you can use most any xfmr like a 6.3v filament xfmr, a number of wall wart varieties and so forth. If the question were about a long-term solution I wouldn't say that. Output transformer of any ilk will not prevent you from testing your radio and sallying forth with the restoration. Get 'er working first.
About the field coil. No problem in having a pro rewind it, in fact thats probably the best option but you still need to have some equivalent in the circuit for the aforementioned testing and that means an offboard choke or something.
The two go together in that respect. You need the field coil AND the AF output xfmr to make it work. There's plenty of workarounds...some, ahem, more 'temporary' than others.
