That would not be 'tricky', that would be impossible. All listed jumps land on the outside edge. If a skater want to have the last jump in the combination Salchow or flip, for those jumps the skater needs to be on the inside edge; that's why the skater does the half loop in between. Half look is a full revolution jump which lands on the inside edge, just ready to add the Salchow or flip. If someone did just whatever jump+ normal single loop, then the skater would exit the single loop on the outside edge and therefore would not be able to have the last jump in the combination Salchow or Flip, they would only be able to do loop or toe loop.
Re: 3T+2A instead of the more talked about 2A+3T, why would anyone want to do 3T+2A when 2A+3T brings more points? If you do 3T, you end up on back outside edge, so get forward to do the 2A would need a hop between those two jumps, which means that it would be a jump sequence and not jump combination and it would have value of only 80% of the jump value base. Whereas 2A+3T is a combination so it has the full value.
IS it possible then to do a lutz if u land on a outside edge in jumps?? I don't understand these at all...
