I could but then wouldn't I need to remove the double sided tape and attach again and what if things are not aligned?

Can't you flip the piece and use the routed side as a template, instead of moving the template? That'll guarantee alignment.

Also, longer bits (with longer "cutting length") are dangerous and unstable, even in the best of routers. One problem is the vibrations at the tip of the bit - no bit has perfect balance at manufacturing.
