5x100 to 5x114.3

[ImprezaWRX]

I'm working on a 2009 Impreza WRX and was wondering if it is possible to swap the bolt pattern from 5x100 to 5x114.3 without having to go down the adapter route. Was thinking swapping in STI hubs but couldn't find anything on the spline counts on the stock WRX axles and the STI axles to indicate if that route is viable.

Any help/advice would be massively appreciated.
