We analyse a possible adjustment of Twin Higgs models allowing to have brokenelectroweak (EW) symmetry at all temperatures below the sigma-model scale $\sim1$TeV. The modification consists of increasing the Yukawa couplings of thetwins of light SM fermions. The naturalness considerations then imply apresence of relatively light electroweak-charged fermions, which can beproduced at the LHC, and decay into SM gauge and Higgs bosons and missingenergy. Analysis of experimental bounds shows that such a modified modelfeatures an increased amount of fine-tuning compared to the original Twin Higgsmodels, but still less tuning than the usual pseudo-Nambu-Goldstone Higgsmodels not improved by $Z_2$ symmetry. The obtained modification in theevolution of the EW symmetry breaking strength can, in particular, haveinteresting implications for models of EW baryogenesis, which we comment on.
