Vertical spacing between character and \hat

Question

I am trying to typeset \hat{V} but it turns out not looking right. The hat is too close to the V so it is difficult to decipher the hat on the V. Is there a way to increase the vertical space between the V and the hat?

Thanks

REVISED to work with all mathstyles.

I've set it up so that changing the value of \dyhat changes the vertical shift relative to its default placement. Shown below (for all three math styles) with a 0.067ex shift on the first line, and a 0.2ex shift on the second line. Negative shifts are acceptable. Using a scalable shift measurement like ex's will permit the result to scale to the different math sizes.

\documentclass{article}
\usepackage{stackengine}
\usepackage{scalerel}
\def\stacktype{L}
\stackMath
\def\dyhat{.067ex}
\newcommand\myhat[1]{\ThisStyle{%
              \stackon[\dyhat]{\SavedStyle#1}
                              {\SavedStyle\hat{\phantom{#1}}}}}
\begin{document}
\( \myhat V \)
\(\scriptstyle \myhat V \)
\(\scriptscriptstyle \myhat V \)

\def\dyhat{.2ex}
\( \myhat V \)
\(\scriptstyle \myhat V \)
\(\scriptscriptstyle \myhat V \)
\end{document}
