You could use a custom usertag like the one below.
Set seperateitems to yes in catalog.cfg
and add the tag [basket_combine] at the top of the
basket page.

Note: this worked with MV 3 and 4, have not tried with IC, but
I believe it should work.

UserTag basket_combine Order quantity
UserTag basket_combine Routine <<EOR
sub {
my $cart = $Vend::Items;
# Combine all similar products if attributes match
for (my $x=0;$x < @$cart;$x++) {
  REMAIN: for (my $y=$x+1;$y < @$cart;$y++) {
    # now check if 'code' (sku) matches
    next REMAIN unless ($$cart[$x]{code} eq $$cart[$y]{code});
    foreach (keys %{ $$cart[$y] }) {
	  # now check that all attributes match (except qty of course)
      next REMAIN unless ($_ =~ /quantity/i ||
        $$cart[$x]{$_} eq $$cart[$y]{$_});
    }
    # we have checked all atb's match, so combine item qty's
    $$cart[$x]{quantity} += $$cart[$y]{quantity};
    # now remove this duplicate
    splice(@$cart, $y, 1);
  }
}

return '';
}
