Aquaring of Sberbank on the Joomla website

Good day !

Asked to evaluate the introduction of acquiring in two ways:
1. Using a ready plugin for Joomla – securepayments.sberbank.r...
(the website is not online shop need to connect the basket)

But it is likely that the client will need to accept payment by two entities, respectively, will be two gateways
Would it be possible to make a revision to the plugin under two gateways or, even better,

2. Using one of the available API

securepayments.sberbank.r...
