It is possible to extend Rapid.Space ORS either by making a donation to the Libre Endowment Fund, by purchasing design services to Rapid.Space or by doing it yourself.
Donations to the Libre Endowment Fund are the right approach if one can benefit from tax breaks in France or from the absence of export restrictions for donations. The Libre Endowment Fund will either hire expertise or outsource the design effort for extensions.
Purchase of design services from Rapid.Space is the right approach outside France, especially in EU, Japan or US.
Do it yourself could be the best apprach in countries with government subsidies, as long as some expertise exists for the design high frequency electronics.
