Not throwing off on anything, but I run a Haban 402-D sickle bar on my 73 and that little 7hp has more than enough power. Have you looked at any old pictures of attachments for the Originals? They have the k-161 too and there pretty much wasn't anything you could put on them. I would just give that 7hp a chance. You can find a lot of videos on youtube with 7hp cubs plowing and dozens of other ground engaging things and they aren't hurting for power.
You would be looking at doing a lot of modifications to add an electric PTO unless you found a newer engine with one native, then that would probably be from a quietline and you'd have to modify the mounts to get it to work right on the 73's frame. You can pick up a fresh rebuilt mechanical PTO for a lot cheaper than an electric one.
