Correcting converging verticals/keystoning on APS-C with DIY bellows tilt-shift?

Hi, I've got a wide angle lens that gives me consistent good results, however as soon as I have to tilt the camerea, keystoning troubles me.

Nothing exaggerated, of course can be corrected in post processing, however since I can literally take hours for some still outdoor subjects (tripod, manual focus, test shots, bracketing and what not) until I either give up or am satisfied with the result, I would prefer not soften the image with the post processing keystone correction-distortion.

Do you think I'd use one of the bellows (probably available for macro) widely sold, modify it for a lateral degree of freedom, attach the lens on one end (and use all manual controls since there are no electrical contacts), and then tilt-shift it enough to prevent keystoning? Or would this yield even worse results (softer images, distortion, loss of sharpness) than post-processing?

Thank you

Alfred
