Sounds like a good idea - sentiment is worth something, after all. Wms frames and original Lionel shells as suggested...not really "sentimental", I'd say.
Certainly a motor in each unit, then "lash 'em up" is advisable, as suggested, but, per pulling power, please remember that these locos don't have to pull anybody else's trains (I presume), just yours, and if your trains are not overly large, then the locos will do the job that you want to do. With sentiment.
