Bowser claim/claim order thoughts:
1) If you were to pick Bowser, and then receive a Town alignment, and an active PR - would you not be more quick off the draw when it came to claiming? You have the role and you know what it is going to look like when you claim last right?
2) As Skum - Wait til the back. Important note, wait til the back when you know Kirby is in the game. Situtation one, you are safe because kill back potential. Situation 2, it doesn't work, you still get lynched, take out the Town hammer, and you turn Kirby into Bowser. If Kirby = Town, and we assuming again Skum will not hammer, this is the original Bowser kill back, plus the Kirby death (if it happens), and the Town Hammer kill back (if it happens).... lots of words in a row and I have been known to be overly paranoid, but just saying.
3) As Town - Why wait until the back of order? You create confusion for your team with the fake claim theories that will assuredly come out, and you have to know it will be a town hammer if you go down so why draw more attention then needed?
