Covert RFC Architecture into SOAP

Hello Gurus,

I have architectural question,

We have JCo client side in our Non SAP system which makes RFC calls to S4HANA onpremise,

I understand pros and cons of RFC Vs Webservice,

(RFCs easy to use, fast / Webservice better standards etc)

Whats is easiest way to covert above into SOAP based webservice,

should we replace JCo with JEE webserver and on ABAP side expose RFCs as webservice?

are there better alternatives? would it be beneficial?

Regards,

Niketan
