It depends on the design and adjustment capabilities of the lens cell and how many elements it has. I think a televue with two widely separeated doublets would be difficult. An achromat with push-pull screws to tilt the whole assembly would be a walk in the park.
Tools include cheshire eyepiece, Howie Glatter's parallizer and laser collimator http://www.collimator.com/
