Can I do a YouTube let's play with a slightly modified modpack?

[Handy__Andy]

I had a question (I think this is the right place to ask this): 

I'm thinking of starting a new lets play on my YouTube channel using the Big Dig modpack, but with another mod added (namely "Invasion Mod", you can check out my YouTube channel if you don't know what Invasion mod is (there's a link in my profile page)).

 

So my question is: Is it ok to play an altered version of the modpack on YouTube?

Uhh... why wouldn't it be?

I don't know, but just making sure
