Replying to Upgrading gear - looking for advice

I am looking to upgrade my equipment over this year. I have been shooting with a Canon 60D for the past 4 years and would really like to upgrade to full frame.

I currently shoot about 70% photo and 30% video, but I want to upgrade to a camera that is more rounded for videography, as I am planning on shooting a lot more of it. I have been shooting video on canon DSLRs for about 5 1/2 years. Would like a camera that is good in low light and outdoors. I shoot a lot of skateboarding, skiing, documentary and promotional (social media commercials for small business/ clients.)

If you guys can give me some advice on which lenses I own that translate well to full frame DSLR, and what lenses/model you would recommend me upgrading to. My current budget is around $2,750. The dream would be to upgrade camera model and purchase a well-rounded glass to go with it.

Current list of lenses:
Tokina 11-16MM
Rokinon 8mm Fish
Canon 18-135
Canon 50mm 1.4 F

Not sure how realistic of a budget that is, but I am hoping you guys can give me a better idea of what I am working with. Thank you in advanced.
