Conflict thead function defined in two packages

I’m using both:

usepackage{makecell}
usepackage{tablestyles}

in a *.tex document.

If I use the previously shown order, I got an ! LaTeX Error: Command thead already defined. error on the tablestyles package at line 120:

newcommandthead{%
  tablefontsize{head}
}

If I inverse the two requirement lines such as:

usepackage{tablestyles}
usepackage{makecell}

I got the same error as before but on the makecell package, line 34:

newcommandthead{@ifstar{lettabg@pegapethead@}%
                          {lettabg@petheadgapethead@}}

How could I make use of the two packages without conflicts and without having to touch to their definition styles?
