You could try it for yourself pretty easily.  Here's an easy way to  
find here the "#X connect" message is implemented:

hans at palatschinken:src > grep '"connect"' *.c
g_editor.c:                gensym("#X"), gensym("connect"),
g_editor.c:                        "connect");
g_editor.c:                gensym("#X"), gensym("connect"),
g_editor.c:            binbuf_addv(b, "ssiiii;", gensym("#X"),  
g_editor.c:        gensym("connect"), A_FLOAT, A_FLOAT, A_FLOAT,  
g_readwrite.c:        binbuf_addv(b, "ssiiii;", gensym("#X"),  
m_binbuf.c:                else if (!strcmp(second, "connect")||
m_binbuf.c:                        gensym("#X"), gensym("connect"),
m_binbuf.c:                else if (!strcmp(second, "connect"))
m_binbuf.c:                        gensym("#P"), gensym("connect"),
u_pdsend.c:        sockerror("connect");
u_pdsend.c:        sockerror("connect");
x_net.c:        gensym("connect"), A_SYMBOL, A_FLOAT, 0);

Basically, these two lines are saying that the "connect" message is  
expected to be in 'ssiiii' format. s = symbol, i = integer.  So  
basically, two symbols (#X connect) and four integers (0 1 0 0)
g_editor.c:            binbuf_addv(b, "ssiiii;", gensym("#X"),  
g_readwrite.c:        binbuf_addv(b, "ssiiii;", gensym("#X"),  

First try throwing extra ints in the #X connect messages in  a .pd  
file, and see if that works.  Then try getting those ints in Pd.
