Try using lemon curd and seedless raspberry jam.
You need to ask the customer what they mean. Maybe they mean a thin layer of lemon and a thin layer of raspberry and a thin layer of custard.
Anyway you also need to ask the customer how long the cake has to be out of the fridge before you make an agreement about providing custard filling.
Hi,
The have a bridal request for a 3-tier white cake with a custard filling with lemon and raspberry. I'm not exactly sure how to do this but I'm thinkng of swirling lemon and raspberry jam into the custard filling? Anyone have a better idea? Thanks
I would recommend using shelf-stable "pastry filling" (often called "sleeve filling"), that does not require refrigeration.
Bavarian Cream (for the custard)
Raspberry
Lemon

Do not swirl them all together, simply cut your cakes in half horizontally (tort), and you can create a 4"-5" high cake that has the following layers (construction from bottom to top of cake):
1" cake
Raspberry pastry filling (about 1/8"-1/4" thick)
1" cake
Bavarian Cream pastry filling (about 1/8"-1/4" thick)
1" cake
Lemon pastry filling (about 1/8"-1/4" thick)
1" cake
