"A smaller whizz bang new type of tool that can slip up and down without getting stuck...go invent one mate!"
Unfortunately theres a limit as to how small an area you can jam a bunch of electronics and hydraulics into. Sometimes you can achieve a larger tool/hole clearance by increasing the size of the production hole (eg 8-1/2" to 12-1/4") but there are considerations before doing same....eg some tools won't work in larger hole, other tools will need big bore kits. There's a hole cost factor as well
