yes I have. wound in that manner and as you say the leakage inductance goes up which means regulation goes down. I was actually rather surprised on how much of a difference the pri-sec proximity effected both the output voltage and regulation at line voltages and I was using *gasp* Stamped M6 Laminations so I did have the cross grain issue which may have made things a bit worse. Of course this is a function of all transformers so anything you do to reduce winding to winding capacitance increases leakage so you just have to pick your poison so to speak.
Along the line of the toroids... Antek has a 50VA unit that will fit your needs for $28 and the single secondary winding will be fine for your bridge. I dropped a note to John @ antek about doing a 50VA version with dual secondaries for FWCT use to match his 100VA and 200VA units which are just too big for linestage / phono use.
