The Rokkor should work fine, you might need to pre-focus it to within the focus ballpark. Not sure what EF-LM adapter you purchased, not all of them will be mountable on the TAP. The Leicaist adapters sold by Techart work but are expensive, you can purchase the same adapter on eBay for a much a cheaper price. I'm not sure the use of manual EF lenses are worth the trouble to use on the Teacart. I have a very large collection of Zeiss ZE and Otus lenses however because of the lack of aperture rings on the ZE mounts you won't be able to change the aperture without mounting the lens on a Canon body or a Sony body with a metabones adapter.
I've slowly been collecting some legacy LTM lenses, Canon lenses in particular, they are tiny and work extremely well with the TAP.
I should have read more of that thread before ordering, luckily the nikon and OM will work, canon wont.
