Everything is possible
People with smaller boats are considering it, as are lots of people with RCD C boats.
Your experience and the hardiness of your crew, the ability to carry extra fuel, cruising speeds of all of that lot combined are factors.
As far as equipment I suggest a fixed VHF and radar reflector in addition to all the usual like lifejackets, flares, provisions etc.
If you do feel up to it, you will be made very welcome by all.
