I'd be interested in playing. I have some 3rd and 4th edition materials, but no 5th yet. I haven't played this much (only at cons), and haven't played a magi character yet. I would like to play a magi, maybe I can make one up with the 3rd or 4th edition and with your help "update" him? Or I'm happy to play mundane characters as well. Let me know what you'd prefer. Thanks!
5e is similiar enough to previous editions that the same concepts can, usually, work in any edition. However, the problem with playing a magus is that you will need to reference the spellcasting rules which are sufficiently different that you may be off on level or even, rarely, arts. You will also suffer from not being privy to more subtle differences, like the way magic resistance and penetration works (spell roll-spell level=penetration), new mastery options (fast-casting, multicasting, no voice/gestures, and so on), ceremonial casting, and more; this will lead to suboptimal choices but I think won't be a big difficulty.
I suggest constructing a 4e magus idea, with a list of desired virtues and flaws (don't bother balancing or settling on 10, AM5 balances differently anyway so I'd prefer the most options), signature spells and arts, and so on. I could then convert him to AM5, and note the significance of my choices on rules that differ from 4e.
If you'll build a specialist, I could send you the pertinent spell guidelines for your character, so you could know what you can and can't spont and so on. If the PbP succeeds and is maintained for a long time, I would strongly suggest picking up AM5 yourself, however.
In the short term, I believe an AM4 specialist could be converted and played easily enough.
