In principle, yes: you’d need a transmitter that can accept the output from your wired intervalometer, plus a receiver connected to the camera’s remote port. The problem is that this input/output combination is uncommon, so a ready-made commercial adapter may be hard to find.

A more practical solution is usually to buy a wireless intervalometer/shutter release made for your camera. That gives you the same remote triggering and interval features without needing to cobble together adapters.

Another possible route is some wireless flash trigger systems, since certain models can also trigger a camera shutter. But you’d still need the right adapter to connect your existing intervalometer to the transmitter, and compatibility can be tricky.

So: possible in theory, but for most users it’s cheaper and easier to use a dedicated wireless intervalometer designed for Canon bodies.
