I would do it. It merges and lets you fine tune some of the data in your mods that Wrye Bash can't currently do. But then again, I don't know how much more stable your game is going to be.  Here is the guy who is part of the team that recoded TES4edit for Skyrim, in the video he describes his thoughts and feelings on making a merged patch. And he also demonstrates how to create one. He also has some other INVALUABLE videos on a plethora of awesome information.  Definitely take notice of mods that have "out of order subrecords" warnings. I would go as far to say, to just bite the bullet-- and not use an awesome incredible mod, just because it has that issue.  Don't try and merge VMAD data! It can totally mess up your game, giving rocks and trees NPC data and I guess all other types of wacky stuff. I personally can't wait for TES5edit 3.0.28, which I guess, functionality for VMAD data will be added, along with a couple other things. If you are going to have both a merged patch, and a bashed patch, don't forget to delete the Leveled Item records from your merged patch.
