When you say "route the trem", I'm assuming you are talking about rerouting the body FOR the trem. In this situation, you will need a shorter trem block, other wise, since the trem will NOW sit, recessed into the body, ther is a good chance that the trem block will poke all the way out of the back, springs and all. Since this Kramer is a top0load trem, it probably has a 42 mm trem block. Either find the appropriate, shorter block for this trem, or (and this is probably the more feasible option) find a newer floyd trem, that HAS the shorter block.
