Special Castle tiles for Mario quest

[Nimono]

I'd like to make my own version of Peach's Castle in my Mario quest, but I'd like the castle to use the overworld level palette. The only castle tiles that I have use the Castle level palette (number 3 for me). This prevents me from making a castle courtyard like I want. So, could someone get me some castle tiles that uses Level 0 palette and doesn't look so dark?

Erm, it'd probably help if you took a screenshot of the level 0 palette you're using so people can see how many colors they're able to add, since there aren't a lot of grays in the default 0, as far as I can remember.

Here's the palette:
