MathTime Pro 2 allows that, there are even options \straightbraces and \curlybraces making the braces straight or curly even at small sizes. See <http://www.pctex.com/mtpro2.html>. But that's because each symbol font (such as mt2syt) has two sets of braces, straight at "B9 and "BA, curly at "66 and "67 (and these are Type1 fonts, not OpenType).

So support from the font is required. Looking at §3.3 of lucidaot.pdf, Lucida doesn't seem to offer that through OpenType features, and looking at unicode-math-table.tex, Unicode doesn't seem to have separate slots for curly and straight braces.
