Apologies for the off-topic responses, are you interested in this unit as a unit that takes in RF from a nearby user and puts them on the internet (Allstar link) or are you looking to craft a node that takes signals off the internet and transmits RF to 'hit' a local 4/6m repeater or nearby simplex operators? In other words, are you looking to create an on-ramp into ASL from an RF device, or an off-ramp from ASL to access RF repeaters/nearby operators?
For an on-ramp a few hundred milliwatts RF output might suffice, but for an off-ramp you'd likely be much happier with a high-watt 4/6m radio and a box like the DINAH (??) that connects to an RPi and a radio with a PM6 connector (like the FT-8900 as someone else mentioned for 6 meters). I am unaware of any 4 meter radios with PM6 connectors.
The reason the VHF/UHF SA818 devices are available is because there were/are sufficient commercial applications for a company to design and produce such a 'part', I don't think there is a corresponding commercial market that caused a manufacturer to design a similar module for either the 4 or 6 meter band.

Thanks for all your comments so far everyone.

We¡¯re already using a mixture of URI¡¯s, CM108¡¯s, modified USB Sound cards with Baofengs, Wouxuns, Motorola¡¯s and others and we¡¯re trying to move away from all that. The appeal of the Shari, having the onboard RF from the SA818 is that it takes away all that complexity, cabling, power supplies and cost and standardises the equipment for all users.

It¡¯s an all in one Asterisk solution, like the Shari I¡¯m looking for, but 4m/6m instead of 2m/70cm. I¡¯m quite happy to modify a Shari if I can find a replacement for the SA818, hence my question to the group.

Hopefully that clarifies the question and keeps us on topic, any ideas anyone? ?
