Diff drop - Skidplate and front diff clearance

[Mossyoakglock]

I have coilovers on my truck to level. They gave me a little over 2.5" of lift up front so I installed a diff drop to lower the angles a bit.

 

Because of that, obviously the diff sits lower so I had to also put spacers to drop the skid plate a bit but the diff is still contacting it. There are two holes that are not being used that looks like the are mounting holes for different applications but are not being used on my truck. 

 

In the two pictures are my estimated and possible cut lines to help with some clearance and hopefully not have to drop the skidplate as much. Does anybody see any negatives to cutting this tab off? It looks like I would not be anywhere close to the main housing and affecting the integrity but gain clearance. I'd leave a little bit of the tab and wouldn't grind it flush.
