There are several words I've found that end in っぱち. **Does the suffix have any
special meaning, like がち?**

[「やけっぱち」](http://zokugo-dict.com/36ya/yakeppachi.htm)  
[「うそっぱち」](http://dictionary.goo.ne.jp/jn/19014/meaning/m0u/)  
[「でこっぱち」](http://zokugo-dict.com/19te/dekoppachi.htm)

It also seems that these are na-adjectives, and [it is possible to add さ (for
at least some of them) to turn them into
nouns](http://www.weblio.jp/content/%E8%87%AA%E6%A3%84%E3%81%A3%E3%81%B1%E3%81%A1%E3%81%95).
**Is this addition possible for all っぱち adjectives?**

words suffixes
っぱち suffix - meaning and addition of さ suffix
There is no special meaning. As one of the linked entries says:

> ※「～ぱち」は語感に勢いをつけたり、意味を強調するもので、これ自体に意味はない。また、これを付けることで、特に意味が変わるものでもない。

I guess these might be originally coined as a wordplay so that it sounds like
a person's name. ～はち/～ぱち (八) was a typical male name-suffix in the Edo period
(eg 甚八, 新八). Since ancient times Japanese people often created meaningless
phrases just because they sound nice
([examples](https://ja.wikipedia.org/wiki/%E5%9C%B0%E5%8F%A3)).

I don't think でこっぱち ("forehead") can serve as a na-adjective. For やけっぱち and
うそっぱち, it's technically possible to add さ, but it's not common because they
already have intense meanings (you don't hear 最高さ often, either).

answer
They are all used as intensifiers for noun there. Therefore っぱち itself doesn't
have special meanings like がち(serious?)

Since やけ, うそ and でこ are nouns not adjectivals(na-adjective), You can't add さ
to nominalize them.
