I did Big Beautiful Doll in 1/32 a couple years ago using Eaglecals and the Tamiya kit. It can definitely be done. The decals had to be cut to make up for the compound curves but I don't think that can be helped. The most work had to go in to making it so the cowling could still be removed after it was finished but if I got it done, and I am not the best modeler out there.
Zotz makes a nice set of checkers for the Tamiya 1/32 nose that fit really well and ultimately was the set I had to use, but the pattern is slightly different than BBD's - each plane of that group had slightly different nose checkers. EagleCal has the right pattern, but as you pointed out, it takes a lot of cutting to get them onto the 1/32 Tamiya nose.
Judy had said they were looking into putting out a proper set for the 1/32, but it sounds like they have not done that yet.
