You can (and often have to) do a lot of things with houserules. Distance Strike, f.i., should be pretty easy to adapt from 4th Edition. As far as I remember the power, you can just copy the description and it would work just as well in 5th Edition. With the Buff to Melee Damage, you can even keep the relatively high PP cost.
TMs were in sorry state right until recently, with a very low power level (as long as you donīt abuse the hell out of Sprites) and only a fringe section of the generally underwhelming Matrix SupplementData Trails dedicatet to them. However, the official Errata for the Core Rulebook contains a huge buff for Technos in the Form of adjusted Priorities at Chargen and reduced Drain Fading Values for Complex Forms. Most importantly, the second (I dare to say, "the real") Matrix Supplement Kill Code will hit the shelves soon - and from what Iīve heard so far, it seems to be really really really good, including a huge Technomancer section.
