Must admit I'm not the biggest fan of Jester - it seems to vary a lot from batch to batch, and I find it somewhat one-dimensional. Romney Marsh do/did a beer with it blended with Goldings which was a massive improvement.
The only reason Brewer's Gold is still grown is because Germans love its soft bitterness for lagers, particularly helles, so you could go that route if you want something different.
But both BG and Goldings can be used in just about any British or Belgian style - I'd find it hard to get away from the general pale ale direction though, as it's just my thing.
