It is very early, too early, given the boat and the intended route.
I have clients sailing this route every year, a couple of boats each year over last 7 years or so.
My standing advice is: do not depart before mid-April: big boats with pro crews. Smaller boats and weaker crews not before mid-May.
can be done any time of the year. Not by a pleasure boat with amateur crew though.
If forced to sail early, I would not go as far N as Azores. Your main challenge being lows passing W to E and at times getting way below the islands. These lows drag long tails (fronts) with associated VERY NASTY conditions.
Look up BA NP 136 or else Cornell's book for more feedback.
PS Once done reading this thread, should you feel in need of any further discouragement, feel free to contact me via a pm.
