What's the point in that?

I am a return player and I enjoy all the story FFXIV offers.
If you don't care for story and just want to go to latest expansion, then how about purchase the adventurer's tale in Mogstation?

Honest. I spent a month and I'm still in early HW. The way I see this will take me 3 months or more, unless you play the game full time.
If you don't value MSQs at all, then the time doing them are a waste. You'd be better off jumping to ShB content.
