I see how the MLCS sled turns the piece sideways but I don't see how it angles. I would be a little bit concerned without trying it with whether the inevitable chatter you get using a router bit would cause the plastic to vibrate, possibly setting up a resonant wave that would amplify it. It wouldn't have that problem on a table saw. The infinity one is more basic and looks more rigid. Here is the original that it's modeled after and I really don't see much improvement over it: https://www.ebay.com/itm/DELTA-Univ...:qHIAAOSwHodc3z31:sc:USPSPriority!35051!US!-1 I have one and it will still be functional 300 years from now. You might be able to wear the guide bar out but it's easily replaceable. I've seen home made ones which you can probably find by searching tenoning jigs. The easiest ones to use ride against the fence on a TS instead of being guided by the slot which can make set up easier. The Delta one can be a PITA to get dialed in. I saw one at a woodworking show once that was pretty slick made by Dave Wooland from somewhere in Ontario up here. He invented the Accusquare fence too which I have one of and highly recommend.
If you wanted to make one that tilts it wouldn't be that hard. I'd probably use a piano hinge between the plates and add ends with radiused slots so that a carriage bolt would fit in to lock them in position.
I don't see why they wouldn't work for the joints you mentioned.
