Help finding new camera body compatible with EOS 60D lenses and accessories

[RaifeBlakeVtM]

Greetings, so I’m a relatively amateur photographer, and stepped away from much photography for quite a while, but hoping to pick it back up some.  
My current camera is an EOS 60D and I have several lenses, filters, an extended battery grip, and a couple of flashes.  Given how expensive these can be to replace I’m really hoping there’s a current model where most or all of these things will still be compatible.  What’s your best advice?

Thanks in advance!

"...you have to make sure that the new lenses have the same size as the filters you have..."

...or use a step down ring.

A year ago I bought some infrared filters. I bought the largest diameter filter size for my current lenses and then got a couple step downs. Yeah, it looks a little jankety in use, but that approach worked flawlessly.
