The major problem there is that we only ever had 263 RHD '32's imported to the UK to start with..Be easier if you started with a SLK32 base. All the extra bits for the supercharger, intercooler, secondary air pump relocation and et al is already done for you.
Last I checked, secondary air pump for any of the supercharged 112/113 cost $600 before markup. You have one lying around? 😳
