I'm in much the same boat. My module substitutes the outside  
listening port in the post_config handler:

static int bn_post_config(apr_pool_t *pconf, apr_pool_t *plog,  
apr_pool_t *ptemp, server_rec *s)
     bn_cfg *cfg;
     server_rec *swalk;

     for (swalk = s; swalk; swalk = swalk->next) {
         cfg = BNSrvConfig(swalk);
         if (cfg->enabled) {
             swalk->port = cfg->listenport;
     return OK;

This has been lightly tested and is based on ap_get_server_port  
looking in that particular place first. So far no horrible side  
effects have been observed.

Do you do more/different things?
