Charnging LFP from two alternators

Hi everybody. I need to charge a Li battery bank from 2 different alternators. System configuration is as follow:

Engine 1 24V 60A alternator with internal regulation connected to its start lead battery

Engine 2 24V 60A alternator with internal regulation connected to its start lead battery

House battery back is 2 x 25,6V LPF Smart 200Ah with Ve.BUS BMS.

The idea is to send two alternator positive to the busbar and put a cyrix Li-charge between them and the lithium battery bank. is there any synchro issues?

Boat owner would like to use Buckboost but I have no knowledge ho to manage with two alternators. Do you have any advise?

@Bocas_Uflex We use our alternator controllers that sit on CANbus and have a master slave option. We have perfected the configuration for Victron Lithium with the Mini-BMS output pushing both controllers to Float mode in the event that volatage detection had not already done that. Have completed many jobs. We are a Victron Dealer in Australia.
