I agree with Laura. If a group of steps are causing problems (rather than simply not looking great) it could be important to get at the root of the problem. If they're put to one side, the problem is still there.
This has happened to us - we had a big problem with a short segment of tango. but, after trying a few other things, we went back to it and resolved the problem. It can be a very simple thing holding you back.
On the other hand, it's pointless for a very tall couple to try something which will only work well for a very short couple. In other words - some limitations are fundamental.
Remember - you learn most when thnigs go wrong
