Don't even do this.
When your lawyer shows up and tells you to STFU, your earlier statement can come back to haunt you -- "well, Mr. Smith, you were willing to talk until you talked to your lawyer, weren't you"
There's a reason the Miranda warning starts out "YOU HAVE THE RIGHT TO REMAIN SILENT."
"ANY THING YOU SAY CAN AND WILL BE USED AGAINST YOU" That's "ANY THING", so just STFU.
Prosecution will most likely not be permitted to bring up during trial that you invoked your 5th in a way that makes you sound guilty for invoking your 5th.
Example: The defendant must be guilty because he refused to talk to police by invoking his 5th amendment right.
