It really depends of how much bandwidth your BT adapter can provide. I have an Atheros AR3012 BT adapter bundled in Atheros AR5B22 combo card and it uses the default MS Stack, using 4 regular Wii Remotes (each one with an attached Wii Motion Plus adapter and a Nunchuck) it worked without any troubles...
