Should be.

Currently, BSSID is only forced for ap_scan=1 mode, i.e., in ap_scan=2
the bssid value in configuration may end up being ignored. I have not
tested this, but it might be enough add following line into 
wpa_supplicant_associate() to do this for ap_scan=2:

if (ssid->bssid_set)
	params.bssid = ssid->bssid;

This would be added to the !bss case which is used in ap_scan=2:

    if (bss) {
	params.bssid = bss->bssid;
	params.ssid = bss->ssid;
	params.ssid_len = bss->ssid_len;
	params.freq = bss->freq;
    } else {
	/* add here.. */
	if (ssid->bssid_set)
	    params.bssid = ssid->bssid;
	params.ssid = ssid->ssid;
	params.ssid_len = ssid->ssid_len;
