Speculation, below
We can clearly spot big similarity with MEKO A200 Valour-class and (said) MAKO-A100 Tamandare-class. It could be chance, or just mistaken numbers, but, I'm guessing Tamandare-class is more a A200 hull than a A100 hull. If so, Tamandare-class can be a good candidate to understand Atlas UK T31e proposal.
Main armaments (76mm, 12 CAMM, hull-sonar FTR, helo) are compatible with T31e RFI. Just add 7-10 m hull section in the middle to increase RHIB carriage (and maybe a funnel?), it is already a good T31e candidate?
