with libipq you can modify the payload of the packet :
Take from man page :
int ipq_set_verdict(const struct ipq_handle *h, ipq_id_t id, unsigned
int verdict, size_t data_len, unsigned char *buf);
if data_len is not 0 and buf is not NULL, the header and payload of the
packet get replaced by the datas pointed by buf.
