it there anyway to have it display longer without increasing the boot time?

Well, you could do the thing I suggested about a custom kernel that displays ONLY the custom logo. Then it would stay on the screen longer without increasing the boot time.

Or, if you want, you can put your own init script into place that pauses before it launches the player app. If I recall correctly, the custom logo stays on the screen right up until the player app grabs the display. So anything you do in the init script which delays the starting of the player app without writing to the screen would make your custom logo stay up longer. But that would increase the boot time.
