Random idea I had for a feat.

Enchant Broom [General]
Prerequisites: Caster level 6th, Ride 1 rank
Benefit: In a ritual lasting 1 hour, you may enchant a broom with the power of flight. This broom must have been in your possession for 24 hours beforehand. You may only have one such broom enchanted at a time, but the broom's powers fade if it is separated from you for more than 24 hours. The broom can serve as a mount for you (and only you), flying as if a permanent overland flight spell were cast on it; the broom's speed increases by +5ft for every 2 caster levels above 6th. This "mount" is considered trained for war, but if you are knocked unconscious while riding you automatically fall and the overland flight effect ends.
Special: You may choose to enchant a broom sturdy enough to function as a quarterstaff, in which case it is treated as a magic weapon for the purpose of overcoming damage reduction (and can be enchanted as a magic weapon as normal). However, it cannot be wielded as a weapon while ridden.
Special: You may treat this feat as Craft Wondrous Item for the purposes of meeting prerequisites.
