[Scip] Is using a subset of SCIP (e.g. B&B) possible to extend Soplex capabilites for limited MIP functionality?

Hi all, I'm working on a Microsoft .NET wrapper for Soplex but I need a fairly limited MIP solving capability. It's for a specific project to aid researchers into Power Grid modelling (an Academic version of Plexos for Power Systems) but could be used by other .NET Applications in the future. The LP solving is working fine but from time to time (rarely enough) I need to specify some of the variables as integer. I'm considering switching between calling SCIP and Soplex depending on whether I have integer constraints to get the code working (though there would be a lot of overhead using SCIP in this manner). Alternatively it might make sense to rewrite my interface methods to always use SCIP (even if I'm dealing with LP solving)? My intuition tells me that the full SCIP package would probably be overkill for this limited case and was wondering if I could hook in at a lower level (maybe using a plug-in). I'm really hoping for some guidance that might point
me in the optimum direction before I launch into development of something that might need to be reworked. Any suggestions would be greatly appreciated.
