Just of the top of my head, using ugly string mixins, this:
auto myConverterFunc(Args...)(Args args)
{
        string genCode()
        {
            string code = "targetFunction(";
            foreach (i, Arg; Args)
            {
                static if (is(Arg == bool))
	            code ~= format("cast(ubyte)args[%s]%s", i, i == 
Args.length ? "" : ",");
                else
	            code ~= format("args[%s]%s", i, i == Args.length ? 
"" : ",");
            }
            code ~= ");";
            return code;
        }
    mixin(genCode());
}

void targetFunction(ubyte i, ubyte j, uint k, int l)
{
        writefln("i : %s, j : %s, k : %s, l : %s",i,j,k,l);
}

void main()
{
        myConverterFunc(true,false,10,20);
}

Thanks. Yes that is one approach. I figured out another approach 
that seems decent:

auto targetFunctionProxy(Args...)(Args args)
{
    import std.meta;
    return targetFunction!(ReplaceAll!(bool, ubyte, Args))(args);
}
