QR sliding dropouts for Pipedream frames?

Long shot, but does anyone know if QR dropouts can be sourced for newer Pipedream frames with 142mm rear ends? None on the site and I've had no response from Alan or Mike yet

The sliders look like this, which unfortunately is (I think) a little different to Paragon Machine Works sliders

I never had a great deal of success finding replacement dropouts for my Sirius (S3 I think). According to Pipedream they're not Paragon dropouts.

My old S3 frame has QR dropouts and this page - Hangers & Sliders (pipedreamcycles.com) suggests that the S4 dropouts might be the compatible with newer frames (IIRC the only difference between the S3 & S4 was a tapered headtube so the S3 dropouts may also work?). The S3 was standard 135mm spacing though.

Alan once told me that Pipedream bikes were made in the same factory as Konas and that some Kona dropouts would work (but this was quite a while ago and pre-Moxie/S5 etc.). The page linked to above also mentions Kona dropouts.

I  think that it might be a bit of a guessing game for you though.

Thanks PJ. Yes I'm fairly certain my Sirius 4g has the same dropouts as the Alice and hence also the newer Sirius and the Moxie

The problem is that I think the Kona dropouts (the newer Unit and Honzo dropouts) are only compatible with the older Sirius, going on the below pic at least

Then the older Kona's seem to be Paragon dropouts (which are the same as my Soma ones on my other bike, but look quite different from my Sirius ones)

So, while sourcing any of those Kona dropouts is relatively easy, finding something that fits the newer Pipedream's seems difficult. RSD seem to use the same design as Pipedream, but no QR version from them from what I can tell

The other option, which must exist, is some sort of insert to shim down the 12mm sliders to 10mm
