It's a wonderful goal. The Pacific Cup back in 1992 was my first ocean crossing. Since then, my husband and I have sailed short handed all over the south pacific, NZ & to the islands more than 7 times, Atlantic 3 times, the med etc etc. That one, lovely downhill passage changed our lives forever.
I'd say go for it, but...reach for the stars with your feet firmly on the ground. If you're not comfortable in fixing gear, find someone who is and take them with you. Don't go out to sea unprepared. It is just plain silliness.
The Pacific Cup is not as serious as the Transpac is. Why not go in the fun race - Pacific Cup? Take other sailor friends (with skills) and share in the experience.
It will change your life.
All the best to you.
