The only issue with them in series is they are big and bulky, so you probably need to figure out a way to support them to do that. That's where it gets a little tricky -- can't use plastic, or at least not near the resistors, it'll melt. You might make a plastic base to hold them, but then use wood for the R's to rest on (at just a couple of points). At least if you get it too hot, you get some warning that way.
Power rating of two is twice one (assuming they are the same R and so split up the dissipation evenly).
100k might be on the small side for a new system break-in -- you'll have to be extra careful, and hope that the peak current won't still trip the arc detector in the supply -- and shut you right back down. I don't have the info on your spellman on how big the R has to just eliminate the arc trip sense, but it's probably in the couple hundred K range.
Posting as just me, not as the forum owner. Everything I say is "in my opinion" and YMMV -- which should go for everyone without saying.
