Hi anomatron,
I founded solution for your problem, it is not simple and it is not final. Requires a lot of changes. I hope you will manage to follow steps, and hope this is what you want.
1. Need to go to Extensions - Template - and chose your default (I worked with T3-blank-home1)
2. Go to Layout
3. Save as Copy (do not do this with your default template so you can start over if somethings go wrong)
4. In this step we need to get rid of 'header' which contains Logo and Search module
5. On your FTP find joomla-root-folder\templates\t3_blank\tpls
6. Open newly created 'Save as Copy" *.php file (see step 3)
- find <?php $this->loadBlock ('header') ?>
- delete it
- find <?php $this->loadBlock ('mainnav') ?>
- rename 'mainnav' with 'mainnav-carousel'
- save
7. Go to joomla-root-folder\templates\tpls\blocks
- find mainnav.php
- duplicate it and rename second file to mainnav-carousel
- open mainnav-carousel and in it paste this code
<?php

8. Go back to your Joomla! backend
9. Extensions - Template - Injection
10. Paste this code Before </head>
<!-- Carousel -->
<div id="myCarousel" class="carousel slide">

/* CUSTOMIZE THE CAROUSEL
-------------------------------------------------- */
/* Carousel base class */
.carousel {
margin-bottom: 60px;
}
.carousel .container {

z-index: 9;
}
.carousel-control {

.carousel-caption .btn {

/* CUSTOMIZE THE NAVBAR
-------------------------------------------------- */
/* Special class on .container surrounding .navbar, used for positioning it into place. */
.navbar-wrapper {
position: absolute;
top: 0;
left: 0;
right: 0;
z-index: 10;
margin-top: 20px;
margin-bottom: -90px; /* Negative margin to pull up carousel. 90px is roughly margins and height of navbar. */
}
.navbar-wrapper .navbar {
}
/* Remove border and change up box shadow for more contrast */
.navbar .navbar-inner {
border: 0;
-webkit-box-shadow: 0 2px 10px rgba(0,0,0,.25);
-moz-box-shadow: 0 2px 10px rgba(0,0,0,.25);
box-shadow: 0 2px 10px rgba(0,0,0,.25);
}
/* Downsize the brand/project name a bit */
.navbar .brand {
padding: 14px 20px 16px; /* Increase vertical padding to match navbar links */
font-size: 16px;
font-weight: bold;
text-shadow: 0 -1px 0 rgba(0,0,0,.5);
}
/* Navbar links: increase padding for taller navbar */
.navbar .nav > li > a {
padding: 15px 20px;
}
/* Offset the responsive button for proper vertical alignment */
.navbar .btn-navbar {
margin-top: 10px;
}
</style>
11. This code worked without carousel javascript, if you encounter slide problems add this after </style> in Injection
<script>
jQuery(document).ready(function(){
jQuery('#myCarousel').each(function(index, element) {
jQuery(this)[index].slide = null;
});
jQuery('#myCarousel').carousel('cycle');
});
</script>
12. That should be it. I repeat, this is not final solution and it has a lot of room for improvement.
In attached file you can see how it looks like, and you can find slider photos. Photos needs to be in joomla-root-folder\images\slide
