Feasible? I've quickly looked at the documents you linked, and they don't really state anything beyond "use IPsec for GTP". Specifically, the do not specify how to do key distribution, how to set up the SAs, whether they use a standard IKEv2 or something else, ... As Linux has a fairly complete IPsec implementation consisting of the kernel-level IPsec transforms with its netlink interface and e.g. the Strongswan userland, I don't really think there is anything that would need to be done in addition to configuring both this IPsec stack and OpenGGSN. So what exactly would you want to do?
