LoRaWAN Repeater

I’m having a challenge to communicate a LoRa network in a very distant range, in a Brazilian florest, and I need to build a LoRa repeater. I know that by default the LoRa can’t repeat a package, however, my scenario is a very low density network and has no network around that use the same frequency (it is a florest scenario).
I’m thinking of building a gateway with the entire LoRaWAN stack, and store the messages and send it to another gateway in a time window (every 2 hour, for example).
My question is: Do you think that the LoRaServer could solve my problem?
Is it possible to use it on raspberry board?

Thanks,
