Bridge Rectifier Challenge - Viewpoints Welcome!

Hi fellow inmates

I'm in the midst of upgrading several components in an op-amp-based, full-dual-mono MC (60dB gain) phono stage (sorry haven't got access to schematic and really can't name the brand). The signal/RIAA aspect is fine. The PS area presents one real challenge - 2 Vishay-General Semiconductor B40 C1500G bridge rectifiers, one per channel (these have four legs). Obviously the intention is to somehow shoe-horn a compact Hexfred/HyperFred/Cree SiC schottky module into an extremely small area on the PCB (approx 12mm x 12mm). Any suggestions?

(Following the bridge rectifiers are 2 x 2200uf filter caps per channel, then 2 x ST L7815CV regulators per channel, then several small filter caps (max 2.2uF) before 15V DC is fed through to the RIAA/signal circuit....a circuit designer friend took one brief look at the current PS circuit setup and stated, "you should try to eliminate any ringing and noise..." I thought maybe with all that cap filtering, PS noise should be somewhat subdued?)
