Sounds good. Feel free to pick your starting spells.
Also, feel free to use the cantrip rules:

There is also an expanded spell list which (I believe) should be fine to use:

Also, the 5e character sheets use a different schedule for calculating ability modifiers than basic fantasy. This is especially relevant to your spell count. Nevertheless, I think instead of fighting with the character sheet, we should just go with the 5e ability modifier schedule. What do you think?
