Interesting. Although I've never tried it, I was under the impression that one could simply use the uprights from the super on the pacemaker. Is that the case? I've never found a decent super for sale at a reasonable price so, have not tried.
I've also thought about having a machinist fab a slightly modified pacemaker upright. It easy to see that, in order to achieve a more useful front tilt range of motion on the pacemaker, one would only need to extend the circle at the base of the upright on the pacemaker front standard....again, I've no pressing (pardon the pun) need for front tilt on the crown graphic and so have not pursued this too far.
